2NUMERICAL STUDIES ON RESONANT AND ENHANCEMENT EFFECTS FOR COUPLING OF MICROWAVE PULSES INTO NARROW SLOTS显示文摘In this paper, modifications to the finite-difference time-domain(FD-TD) method for modeling microwave pulse coupling into a slot, which is much narrower than one conventional FD-TD cell, are discussed. The coupling process of microwave pulse into a slot is studied by using the modified FD-TD method, and the dependence of microwave coupling on slot sizes, the carrier frequencies and the polarization directions of the incident waves is analysed. Resonant and enhancement effects which occur in this process are observed. The condition at which the resonant effect takes place is also presented.Wang Jianguo Yu Hanqing Liu Guozhi Chen Yusheng Fan Ruyu (Northwest Institute of Nuclear Technology, Branch 15, P. O.

5High reproducibility and sensitivity of bifacial copper nanowire array for detection of glucose显示文摘The ordered bifacial copper nanowire array(Cu BNWA) was synthesized by a template assisted electrochemical deposition method.The morphology and structure of the as-prepared samples were investigated by field emission scanning electron microscope(FESEM) and X-ray diffraction(XRD).The results show that the ordered Cu nanowire array with uniform geometrical dimensions covered both side of the Cu substrate.When used as the electrode for glucose detection,the minimum detectable concentration of glucose can be reached as low as 0.2 mM.Impressively,the sample still showed high sensitivity and stability for glucose detection after two months placement in ambient environment.These excellent performances of the Cu BNWA make it a promising non-enzyme glucose detection sensor for various applications.Hanqing Zhang Yining Wang Xuesen Gao Zhuo Gao Yan Chen 2017Progress in Natural Science:Materials International2017,27,3:2
6Nutrient mTORC1 signaling contributes to hepatic lipid metabolism in the pathogenesis of non-alcoholic fatty liver disease显示文摘Energy metabolism is maintained by the complex homeostatic system in multiple cells and organs involving“nutrient signaling”or“nutrient sensor”.Overnutrient-induced chronic metabolic diseases,as the hallmarks of the 21st century’s public health,are growing threat worldwide.In the past two decades,non-alcoholic fatty liver disease(NAFLD)has emerged as the most prevalent form of chronic liver dis-ease,affecting globally,and increases the risk of incident obesity,type 2 diabetes,and insulin resistance.NAFLD begins with the excessive triglyceride accumulation in hepatocytes,and develops to hepatocel-lular steatosis with inflammation(non-alcoholic steatohepatitis,NASH),fibrosis,cirrhosis,and ultimately hepatocellular carcinoma(HCC).The liver is the central mediator of lipid metabolism by regulation of fatty acid(FA)uptake,manufacture,store,export,and oxidation in response to physiological fluctuations of nutrient.Sterol regulatory element-binding protein c(SREBP-1c)-mediated de novo lipogenesis(DNL)is an important nutritional regulator in biosynthesis of FAs and triglyceride in the liver.Mechanistic target of rapamycin complex 1(mTORC1),as a central hub of nutrient signaling,controls cellular metabolism and growth mainly via increasing anabolic processes and inhibiting catabolic processes in response to physiological fluctuations of nutrient.mTORC1 activation contributes to regulation of DNL by increasing SREBP1 transcription,which contributes to NAFLD pathogenesis and accelerates NAFLD-related HCC development.In this review,we provide the comprehensive understanding of the molec-ular mechanism of SREBPs and autophagy to control hepatic lipid homeostasis under nutrient availability in physiological and pathophysiological states,and highlight how nutrient mTORC1 signaling coordi-nately to integrate the lipid metabolic regulation and therapeutic targets in NAFLD and HCC.Hanqing Chen 2020Liver Research2020,4,1:2

8Two-stage degradation and novel functional endothelium characteristics of a 3-D printed bioresorbable scaffold显示文摘Bioresorbable scaffolds have emerged as a new generation of vascular implants for the treatment of atherosclerosis,and designed to provide a temporary scaffold that is subsequently absorbed by blood vessels over time.Presently,there is insufficient data on the biological and mechanical responses of blood vessels accompanied by bioresorbable scaffolds(BRS)degradation.Therefore,it is necessary to investigate the inflexion point of degradation,the response of blood vessels,and the pathophysiological process of vascular,as results of such studies will be of great value for the design of next generation of BRS.In this study,abdominal aortas of SD rats were received 3-D printed poly-l-actide vascular scaffolds(PLS)for various durations up to 12 months.The response of PLS implanted aorta went through two distinct processes:(1)the neointima with desirable barrier function was obtained in 1 month,accompanied with slow degradation,inflammation,and intimal hyperplasia;(2)significant degradation occurred from 6 months,accompanied with decreasing inflammation and intimal hyperplasia,while the extracellular matrix recovered to normal vessels which indicate the positive remodeling.These in vivo results indicate that 6 months is a key turning point.This“two-stage degradation and vascular characteristics”is proposed to elucidate the long-term effects of PLS on vascular repair and demonstrated the potential of PLS in promoting endothelium function and positive remodeling,which highlights the benefits of PLS and shed some light in the future researches,such as drug combination coatings design.Tieying Yin Ruolin Du Yang Wang Junyang Huang Shuang Ge Yuhua Huang Youhua Tan Qing Liu Zhong Chen Hanqing Feng Jie Du Yazhou Wang Guixue Wang 2022Bioactive Materials2022,7,4:2

11Iron metabolism in non-alcoholic fatty liver disease: A promising therapeutic target显示文摘Non-alcoholic fatty liver disease(NAFLD)has become the most common cause of chronic liver disease worldwide,and is closely associated with the increased risk of the prevalence of obesity and diabetes.NAFLD begins with the presence of>5%excessive lipid accumulation in the liver,and potentially de-velops into non-alcoholic steatohepatitis,fibrosis,cirrhosis and hepatocellular carcinoma.Therefore,insight into the pathogenesis of NAFLD is of key importance to its effective treatment.Iron is an essential element in the life of all mammalian organisms.However,the free iron deposition is positively associated with histological severity in NAFLD patients due to the production of reactive oxygen species via the Fenton reaction.Recently,several iron metabolism-targeted therapies,such as phlebotomy,iron chela-tors,nanotherapeutics.and ferroptosis,have shown their potential as a therapeutic option in the treatment of NAFLD and as a clinical strategy to intervene in the progression of NAFLD.Herein,we review the recent overall evidence on iron metabolism and provide the mechanism of hepatic iron overload-induced liver pathologies and the recent advances in iron metabolism-targeted therapeutics in the treatment of NAFLD.Hanqing Chen 2022Liver Research2022,6,4:1

14Low-temperature and high-voltage planar micro-supercapacitors based on anti-freezing hybrid gel electrolyte显示文摘Micro-supercapacitors(MSCs)are considered as highly competitive power sources for miniaturized electronics.However,narrow voltage window and poor anti-freezing properties of MSCs in conventional aqueous electrolytes lead to low energy density and limited environmental adaption.Herein,we report the construction of low-temperature and high-energy-density MSCs based on anti-freezing hybrid gel electrolytes(HGE)through introducing ethylene glycol(EG)additives into aqueous LiCl electrolyte.Since EG partially destroys hydrogen bond network among water molecules,the HGE exhibits maximum electrochemical stability window of 2.7 V and superior anti-freezing features with a glass transition temperature of-62.8℃.Further,the optimized MSCs using activated carbon microelectrodes possess impressive volumetric capacitance of 28.9 F cm^(-3)and energy density of 10.3 mWh cm^(-3)in the voltage of 1.6 V,2.6 times higher than MSCs tested in 1.2 V.Importantly,the MSCs display 68.3%capacitance retention even at-30℃ compared to the value at 25℃,and ultra-long cyclability with 85.7%of initial capacitance after 15,000 times,indicating extraordinary low-temperature performance.Besides,our devices offer favorable flexibility and modular integration.Therefore,this work provides a general strategy of realizing flexible,safe and anti-freezing microscale power sources,holding great potential towards subzero-temperature microelectronic applications.Manning Chen Xiaoyu Shi Xiaolei Wang Hanqing Liu Sen Wang Caixia Meng Yu Liu Liangzhu Zhang Yuanyuan Zhu Zhong-Shuai Wu 2022Journal of Energy Chemistry2022,31,9:1

16Thickness evolution of graphite-based cathodes in the dual ion batteries via in operando optical observation显示文摘Graphite has been currently considered as a promising cathode material in dual ion batteries(DIBs)due to its unique features of sp2 hybridized carbon and stacked two-dimensional layered structures.However,unexpected volume/thickness changes in the graphite cathodes,induced by the intercalation/deintercalation of anions with large molecular size have been known to be a critical problem in designing DIB cells.To understand the volume/thickness changes in the DIB electrodes,in operando optical observing apparatus has been employed to observe the cross-section view of a graphite-based cathode upon cycles in the present work.The observation suggests that the cathode initially presented a huge irreversible thickness change(60%),and such thickness variation was prone to reduce and remain <20% in the following cycles.The results from both in operando observation and electrochemical characterizations collectively indicate that the greater thickness variation at initial cycle should be attributed to both anion intercalation into graphite-based cathodes and irreversible decomposition of chemical components in the DIB system.The method here highlights a universal route for fundamentally understanding the electrodes of huge volume variation.Na Li Yaoda Xin Haosen Chen Shuqiang Jiao Hanqing Jiang Wei-Li Song Daining Fang 2019Journal of Energy Chemistry2019,28,2:1

18Ecdysone and Insulin Signaling Play Essential Roles in Readjusting the Altered Body Size Caused by the dGPAT4 Mutation in Drosophila显示文摘Body size is one of the features that distinguish one species from another in the biological world. Animals have developed mechanisms to control their body size during normal development. However, how animals cope with genetic alterations and/or environmental stresses to develop into normal-sized adults remain poorly understood. The ability of the animals to develop into a normal-sized adult after the challenges of genetic alterations and/or environmental stresses reveals a robustness of body size control. Here we show that the mutation of dGPAT4, a de novo synthase of lysophosphatidic acid, is a genetic alteration that triggers such a robust response of the animals to body size challenges in Drosophila. Loss of dGPAT4 leads to a severe delay of development, slow growth and resultant small-sized animals during the larval stages, but results in normal-sized adult flies. The robust body size adjustment of the dGPAT4 mutant is likely achieved by corresponding changes in ecdysone and insulin signaling, which is also manifested by compromised food intake. Thus, we propose that a strategy has been evolved by the animals to reach final body size when challenged by genetic alterations, which requires the coordinated ecdysone and insulin signaling.Yan Yan Hao Wang Hanqing Chen Anya Lindstrm-Battle Renjie Jiao 2015Journal of Genetics and Genomics2015,42,9:1

20A Thermoregulatory Flexible Phase Change Nonwoven for All‑Season High‑Efficiency Wearable Thermal Management显示文摘Phase change materials have a key role for wearable thermal management,but suffer from poor water vapor permeability,low enthalpy value and weak shape stability caused by liquid phase leakage and intrinsic rigidity of solid–liquid phase change materials.Herein,we report for the first time a versatile strategy for designed assembly of high-enthalpy flexible phase change nonwovens(GB-PCN)by wet-spinning hybrid grapheneboron nitride(GB)fiber and subsequent impregnating paraffins(e.g.,eicosane,octadecane).As a result,our GB-PCN exhibited an unprecedented enthalpy value of 206.0 J g^(−1),excellent thermal reliability and anti-leakage capacity,superb thermal cycling ability of 97.6%after 1000 cycles,and ultrahigh water vapor permeability(close to the cotton),outperforming the reported PCM films and fibers to date.Notably,the wearable thermal management systems based on GB-PCN for both clothing and face mask were demonstrated,which can maintain the human body at a comfortable temperature range for a significantly long time.Therefore,our results demonstrate huge potential of GB-PCN for human-wearable passive thermal management in real scenarios.Hanqing Liu Feng Zhou Xiaoyu Shi Keyan Sun Yan Kou Pratteek Das Yangeng Li Xinyu Zhang Srikanth Mateti Ying Chen Zhong‑Shuai Wu Quan Shi 2023Nano-Micro Letters2023,15,2:1
